Distribution of combination therapy (CT) according to activities of daily living (ADL) in each ejection fraction (EF) category. Among patients with HF with reduced or persevered EF (HFrEF and HFpEF, respectively), the highest proportion of CT prescriptions was found for the independent outdoor walking group, and the rate of CT prescription decreased with declining ADL. In patients with HF and mid-range EF (HFmrEF), the highest proportion of CT prescriptions was for the independent indoor walking group.
